Abstract

Provided are a non-aqueous electrolyte, which includes an organic solvent, a lithium salt, and a phosphorus compound including an acryloyloxy group, and a lithium secondary battery including the non-aqueous electrolyte. Since the non-aqueous electrolyte includes the phosphorus compound to form a stable solid electrolyte interface (SEI) on an electrode during charge and discharge of the battery, initial capacity and power characteristics at room temperature and low temperature as well as lifetime characteristics of the battery may be improved.
